Ideal Top Cover Gasket 100936

The Ideal 100936 is a top cover gasket used on Ideal Commercial boiler assemblies. It sits between the top cover and the main body of the appliance, forming a compression seal that keeps flue products and heat where they belong and stops water or condensate tracking across the joint face.

It is supplied as part of the Ideal Commercial Boiler Spares range and is listed against the Concord Super Series 3 and Super Series 4 appliances in both horizontal and vertical configurations.

• Water staining, weeping or a visible damp track around the top cover joint
• The gasket has hardened, flattened or cracked and no longer springs back when compressed
• Combustion readings drift or the appliance shows signs of leakage at the cover face after servicing
• The cover has been removed for inspection or cleaning and the old gasket will not reseal
• Crumbling or brittle material found on the sealing face when the cover is lifted

• Confirm the appliance model and serial number against the compatibility list, as Concord Super Series 3 and Series 4 covers differ between horizontal and vertical builds
• Check the alternative number 1175357 against any documentation you hold, in case the part is listed under that reference on older paperwork
• Inspect the cover face and fastenings while the appliance is open, and replace any other seals disturbed during the same job
